Confidence Without Competence? Exploring Gender Gaps in Mathematics Self-Efficacy and Academic Success in Engineering.

Year: 2026

Type: article

Abstract: This repository provides the supplementary research materials associated with the article “Confidence Without Competence? Exploring Gender Gaps in Mathematics Self-Efficacy and Academic Success in Engineering.” In the journal "Cogent Education". The study examined the relationships among diagnostic mathematics performance, mathematics self-efficacy, gender, and first-semester academic outcomes in a cohort of first-year engineering students in Mexico. The repository includes the following materials: Synthetic dataset (syn_data.csv): a privacy-preserving synthetic version of the study database, generated from the original dataset to enable transparent inspection of the analytical structure without exposing participant-level confidential information. Statistical analysis code: R scripts documenting the analytical procedures used in the article, including descriptive analyses, correlation matrices, group comparisons, MANOVA/MANCOVA models, and regression analyses. Synthetic data generation code: R script used to generate the synthetic dataset from the original database. The original dataset contained 777 participant records and variables related to gender, engineering major, differential calculus performance, first-semester grades, mathematics self-efficacy scores, and diagnostic mathematics test results. Because the original database is subject to confidentiality restrictions, it is not made openly available. The synthetic dataset and code are shared to promote transparency, reproducibility, and secondary methodological learning. Data availability statement:The original dataset used in this study is not publicly available due to participant confidentiality considerations. However, the synthetic dataset and the R scripts used for data analysis and synthetic data generation are openly available in Zenodo at: [DOI to be inserted after deposit].
